Value Collection FHS1X0325-050BX M3x0.5 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1X0325-050BX is a metric flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Sized M3x0.5 with an overall length of 25 mm, it features a 90-degree flat head driven by a 2 mm hex socket. The fastener is partially threaded and manufactured from 18-8 austenitic Grade A2 stainless steel, offering solid corrosion resistance in wet, marine, and chemically active environments. It conforms to DIN 7991, making it a direct fit wherever that standard is specified. Machinists, millwrights, fabricators, and mechanical contractors install this type of fastener in panel assemblies, enclosures, and precision equipment where a low-profile head is required.

This screw is suited for general mechanical assembly, equipment fabrication, and maintenance work across a broad range of industries including HVAC equipment manufacturing, electrical enclosure assembly, and light structural applications. Its metric M3x0.5 thread pitch and stainless steel construction make it a common choice where dimensional precision and corrosion resistance both matter. The partially threaded shank provides clamping grip between mated parts while the flat head seats flush in a countersunk hole. These screws are sold at a minimum order quantity of 50 units per order.

Key Features

• 90-degree flat head seats flush in countersunk holes, eliminating protrusion above the mating surface
• 2 mm hex socket drive for precise torque application with standard hex keys or Allen drivers
• 18-8 austenitic Grade A2 stainless steel construction for corrosion resistance in wet and chemical environments
• Conforms to DIN 7991 fastener standard for consistent dimensional compatibility
• Partial threading provides a clamping shank section between fastened components
• Metric M3x0.5 thread for use in metric-spec assemblies and equipment

Compatibility

Designed for use in any metric M3x0.5 threaded countersunk application conforming to DIN 7991, including panel assemblies, precision equipment, and fabricated enclosures that call for a flush flat-head fastener.

Installation Notes

Install using a 2 mm hex key or Allen driver; do not use an oversized driver as it will damage the socket. Ensure the receiving hole is properly countersunk to 90 degrees to achieve full head seating and avoid stress concentration. Verify thread engagement depth meets the requirements of the application before final torque. Stainless steel fasteners are susceptible to galling — apply an appropriate anti-seize compound when working in high-friction or high-torque installations.
